Update: August 22, 2012
4.2 is already out and so I updated the below instructions and updated
the makefile. This time I also took some time to find the exact
dependancies and added that in the makefile.
1. Goto your openwrt compile environment base directory.
2. mkdir package/yate4
3. Download Makefile.yate4.2 to package/yate4/Makefile
Note: if you dont have compiled openwrt in this directory, you might have to build the toolchain before the next step.
4. make package/yate4/compile
5. make package/yate4/install
